UCC27531DBVR 35-V VDD, ndi zotulukapo zogawanika
UCC27531DBVR 35-V VDD, ndi zotulukapo zogawanika
Zithunzi za UCC27531
Dalaivala wotsika mtengo (wopereka njira yabwino yoyendetsera FET ndi IGBTs)
Kusintha kwapamwamba kwa discrete transistor pair drive (kupereka mawonekedwe osavuta ndi owongolera)
TTL ndi CMOS yogwirizana ndi logic logic threshold (yodziyimira payokha yamagetsi yamagetsi)
Zosankha zogawanika zimalola kusintha kwa ma turnon ndi ma turnoff
Zosintha zolowetsa ndi zosasintha
Yambitsani ndi malire ogwirizana ndi TTL
Gwero lapamwamba la 2.5-A ndi mafunde a 2.5-A kapena 5-A sink peak pa 18-V VDD
Kuchuluka kwa VDD kuyambira 10 V mpaka 35 V
Lowetsani ndi kuyatsa zikhomo zomwe zimatha kuyimirira mpaka -5-V DC pansi pa nthaka
Kutulutsa kumakhala kochepa pamene zolowetsa zikuyandama kapena panthawi ya VDD UVLO
Kuchedwa kufalitsa mwachangu (17-ns Zofananira)
Nthawi yokwera ndi kugwa mwachangu
(15-ns ndi 7-ns ofanana ndi 1800-pF Load)
Undervoltage lockout (UVLO)
Amagwiritsidwa ntchito ngati dalaivala wammbali kapena wocheperako (ngati wapangidwa ndi kukondera koyenera komanso kudzipatula kwazizindikiro)
Zosankha za phukusi zotsika mtengo, zopulumutsa malo 5-pin kapena 6-pin DBV (SOT-23)
UCC27536 ndi UCC27537 pin-to-pin yogwirizana ndi TPS2828 ndi TPS2829
Kutentha kogwira ntchito kwa -40 ° C mpaka 140 ° C
Zithunzi za UCC27531
Ma UCC2753x single-channel, oyendetsa zipata zothamanga kwambiri amatha kuyendetsa bwino ma switch a MOSFET ndiIGBT.Pogwiritsa ntchito mapangidwe omwe amalola kuti pakhale gwero la 2.5 A ndi 5-A sink throughasymmetrical drive (zotuluka zogawanika), kuphatikiza ndi kuthekera kothandizira kukondera koyipa, kuyendetsa njanji kupita ku njanji, kuchedwetsa kwakung'ono kwambiri. (17 ns wamba), UCC2753xdevices ndi njira zabwino zothetsera MOSFET ndi IGBT zosinthira mphamvu.Banja la zida za UCC2753x litha kuthandiziranso, kulowetsa pawiri, ndikulowetsa komanso kusasintha magwiridwe antchito.Kugawanika ndi kuyendetsa mwamphamvu kwa asymmetrical kumathandizira chitetezo cha zida motsutsana ndi parasitic Miller turn-oneeffect ndipo zingathandize kuchepetsa kutsika kwapansi.
Kusiya pini yolowetsayo yotsegula kumapangitsa kuti zotulutsa zoyendetsa zikhale zochepa.Mayendedwe amalingaliro a ma driver omwe akuwonetsedwa pazithunzi zogwiritsira ntchito, chojambula chanthawi, ndi tebulo la chowonadi cholowa ndi chotuluka.
Kuzungulira kwamkati pa pini ya VDD kumapereka ntchito yotsekera yotsekeka yomwe imakhala yotsika mpaka voliyumu ya VDD ili mkati mogwira ntchito.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
